Vertebral Artery Sacrifice: Novel Strategy in Treatment of Vertebral Artery Loop.

Background: We report a case of cervical radiculopathy caused by an anomalous vertebral artery (VA) and the efficacy of endovascular vertebral artery sacrifice.

Case Description: A 62-year-old woman was referred to neurosurgery because of an 8- to 9-year history of progressive left C6-7 radiculopathy refractory to other forms of treatment. Radiologic evaluation showed an abnormally tortuous loop of VA at V2 causing direct neurovascular compression at the C6-7 level.
